This large, but readily disintegrating when collected, brown-frosted ‘dog lichen’, is frequent in Ireland on the short turf of rather basic soils. It is usually abundantly fertile with red-brown discs that are often in-rolled. The lower surface, which attaches like velcro, is covered with buff to ochre-coloured veins towards the centre of the thallus. These veins are covered in dark, fluffy rhizinae.
